The Flint Hills International Children's Festival (this weekend) is the latest local fest to offer visitor info via free smartphone app. It comes with an interactive map, schedule of events, links to related social media and even a "virtual photo booth."

"It's the technology that people use to stay connected, to stay informed and find their way to interesting events," said Jake Reint, spokesperson for Flint Hills Resources, which sponsors the children's festival in St. Paul. "We think people will have a lot of fun with it."
